Well there's the obvious unsynched ".txt" file
...there's ".cdg" karaoke +96 data ...other than
that I can only infer the existence of other
more synched or otherwise formatted files.

Sadly I've not looked seriously at the Rockbox code since I was banned from it.
If the main code is THAT tight on space, you will
need to look at more complex options :(
Maybe you could run a "view lyrics" plugin
directly FROM the WPS? rather than embed the
viewer as a funtion INTO the WPS. That will give
you 32768 bytes of RAM to play with, which should
be sufficient to resolve any memory issues you are having.
